TRUCK SIDE FRAME.

To all w 720m it may concern Be it known that I, HARRY E. Down, a citizen of the United States, residing at St. Louis, in the State of Missouri, have invented certain new and usefullmp'rovements in Truck SideFr'ames', of which the following is a specification.

This invention relates to truck side frames, and primarily to pedestal truck side frames. i

Heretofore pedestal truck side frarr ies i ccordingly, such a side frame could not be used .for replacements of arch bars or the standard type of frame, both of which use Master Car Builders journal boxes.

Therefore, one object of this invention is to provide a simple and novel pedestal truck side frame which will accommodate M. C. journal boxes. 5

Another .object is to provide a truck side frame which may be detachably connected to a journal box in a manner to obviate the use of bolts and whereby an emergency fastening is formed should the truck be derailed or lifted from the track by any other These and other objects are accomplished by means of the arrangements disclosed 011 the accompanying sheet of drawings, in

' which- Figure 1 is a fragmentary side elevation of. my improved truck side frame showin its means of attachment to an M. U. B. stand ard journal box; 1

Fig. 2 is a top plan'view of the same arrangement; Q

Fig. 3 is an end view thereof; and

Fig. 4 is a fragmentary side elevation of a truck side frame embodying a modification of my invention.

Thevarious novel features of the invention will be apparent from the following description and the drawings, and will be particularly pointed out in the appended claims.

Referring to the figures of the drawings, it will be noted that I have provided a truck side frame 10 having pedestal jaws 11, the lower ends of which terminate. in laterally extending portions 12, which extend toward each' other lengthwise of the side frame. These extending 'aw portions 12 engage the sides of the M. B. journal box 13 inter- -mediate its ends and more particularly in- Specification of Letters Patent.

ply the side frame to the journal box by a Patented Nov. 9, 1920.

Application filed January 24, 1920. Serial No. 353,861.

.' termediate the vertical planes of the journal box bolt lugs 14. As is apparent from the arrangement disclosed in the figures of the drawings, it would be impossible to ap;

relative vertical movement while the jaw' extensions 12 are intermediate the journal box bolt lugs 14. Accordingly, to apply the side frame to the journal box when the latter is fixed on the journal, the side frame 11 is moved inwardly with respect to the journal box to a point where the relatively narrow jaw extensions 12 may pass vertically downwardly between the inner journal box bolt lugs 14- and, the' dust guard housing 15. lVith the side frame in this position the same may be lowered to permit the jaw extensions 12 to pass vertically downwardly beyond the upper journal box bolt lugs 14, whereupon the side frame may 75 be moved relatively outwardly with respect to the journal box to take its normal operating position. I

It will be noted particularly that the side frame 10 is provided with two projecting members 16 which are properly spaced to pass into the upper bolt openings 17 of the journal box bolt lugs 14. These projecting members are of the same size as the journal box bolts and spaced with'the same centers, and are employed to resist the service stresses and normally prevent relative lateral movement between the truck side frames M and the journal boxes. The journal box here shown is a standard M. C. B. journal box, but it will be understood that the projecting members may extend into openings of other journal boxes for accomplishing the same result.

In Figs. 1 to 3 inclusive the projecting members are bosses integrally formed with the side frame. In Fig. 4 I have shown the projecting members 16 in the form of pins which are cast in the frame; 7

When the journal box 13 and side frame have been moved relatively laterally to a point where the projecting members 16 may assume the proper position with respect to the openings 17 therefor, the side frame is lowered into the position shown in Fig. 1 of the drawings, it being understood that the side frame has been applied to the journal box first by a vertical movement and then by a lateral mt ement in the manner hereinabove considered.

Then the projecting members 16 are located within their associated openings 17, relative lateral mov*ment between the side frame and journal box is prevented. It will be noted that the jaw extensions 12 are spaced from the projecting members 16 vertically an amount to accommodate the journal bo'x lugs 14 in applying the frame to and withdrawing the safe from the ournal box. These projecting members 16 extend downwardly from the upper wall portions by any part other than the axles.

It will be noted that no bolts or other fastenings of any kind are required to hold the side frame in proper position, other than the parts hereinabove specifically set forth, the projecting members 16 extending down into the opening 17 in the journal box lugs and the pedestal jaw extensions 12 bearing against the sides of the box for holding same in properrelation to the side frame.

It will be understood that when it is desired to replace the broken journal box, the same may be done by raising the side frame an amount to properly accommodate the upper journal box lugs 14 between the jaw extensions 12 and the projecting members 16, whereupon the new journal box may be moved-laterally inwardly to the point where on the latter and the dust guard housing,

whereupon theside frame and journal box may be moved relatively to each other to their normal relative positions, said side frame'having projecting members for extending into the bolt holes of said journal box normally to revent relative movement between the side frame and journal box.

2. A pedestal truck side frame having pedestal jaw portions and projecting members spaced from each other, whereby a journal box having lugs may be applied by lateral movement therebetween, said pedes tal jaw portions normally embracing the sides of the journal box and said projecting members extending into the bolt openings in the journal box lugs for normally preventing-relative movement between the side frame'and journal box.
